Re: Oil pump

Wonder where that's coming from?

That's an Oldsmobile high volume oil pump, pickup and while it isn't shown clearly in the photos, it looks like my adapter kit. I do not recognize the milled cut on the end of the oil pump pressure relief spring housing. That's not done on the Melling pumps I supply.

He's asking $500 and my list price for the same setup is $395.

FWIW, I've never seen a plate or body warped enough to leak air. They're usually under the oil level anyway.

The most worn area is usually the lower end of the pump drive shaft and the pump body where the shaft rides.

FWIW, Packard engineers spent a lot of time worrying about the pressure relief valve opening. The first Service Bulletin dealer fix was adding the copper dip tube to keep the opening below oil level in the pan. The second fix was filling the cross pin retaining holes, then drilling and tapping the pressure relief opening for a threaded plug.

It is to be wondered why they did this, as every pressure relief piston I have seen in core engines is always stuck in the bore and requires major effort just to remove it. With that tight fit, how much air could ever enter there?

Very interesting! In all my years of looking at crankshafts, I've never seen one cracked in that fashion. It does appear to be a casting flaw which spread.

Since Packard V8 cranks are still thick on the ground, I'd not chance using that one.

As to grooving the cam journals, I've never seen that done to a Packard V8.

Agree, since it's the main bearings which fail first, why would anyone want more oil to the cam bearings?

The usual answer:

"It worked so well the big corporations bought up the patent and kept it a secret."

Same with water injection. If it were a really workable solution, it would be designed in on each engine or would be government mandated. Just look at diesel engine BlueDef fluid. The owners hate the hassle and the fleets hate the expense, but it's required by regulation.

Good pump, but am not sure they'd fit in a Packard oil pan. The Hash has the sump in a different location.

Hi, Riki,

Looks to be a Hash pump. All the 1956 Studebaker Golden Hawk oil pumps I've seen have a flat plate bottom cover.

Yes, Owen, that oil pan only came on a Hash.

The casting number is above the center exhaust port.

The oil pan and oil pump is substantially different on the Hash varieties.

Supposedly, they also had lower compression ratios, about 7.8. What is the casting number and date on the top rear of the bell housing? Does yours have the '56 heads #6480406CD ?
